IMPROVEMENT IN STEAM-RADIATORS.

Specification forming part of Letters Patent No. 153, 139, dated July14, 1874; application filed February 7, 1874.

CASE A.

To all whom it may concern:

Be it known that I, SAMUELR. WILMoT, of Bridgeport, in the county ofFairfield and State of Connecticut, have invented an Improvement inSteam-Radiators, of which the followin g is a specification:

This invention consists in a steam-radiator,

composed of any number of vertical pipes, not

resents a longitudinal elevation ofa steam-radiator constructed inaccordance with my improvement, and Fig. 2 a longitudinal section of thesame.

A A are the end vertical pipes of my improved steam-radiator-which ishere shown as of a single construction, but-which may be doublethat iscomposed of any number of such structures, arranged one behind theother, or which may be extended to any required length, regardless ofthe number of intermediate vertical tubes A These latter tubes A areconnected alternately with each other at their tops and bottoms, andwith the end pipes A A at their tops, by upper and lower elbows C D, thelower return ones, D, communicating at their bottoms, by drip-openingsor connections 1), with a horizontal base-pipe or conduit, E, extendingbetween the receiving vertical pipe A of the radiator and the outletvertical pipe A for the steam. This basepipe E is in free communicationat its back end by an aperture, c, with the outlet vertical pipe A, butis closed at its opposite end, or only provided with a very contractedaperture, to provide for the escape into it of any water that mightcollect in the bottom of the steam-receiving pipe A.

In this way, or by this construction, it will be seen that a continuouscirculation or flow of the steam from one end of the radiator to theother is kept up, free from any interference by water of condensationforming in the vertical pipes A such water at once escaping by thedrip-openings 1) into the horizontal base E, from whence it is passed orrun outward, and which is not a steam-conduit, or, at least, notdesignedly such.

Instead of the end vertical pipes A A for the admission and escape ofthe steam, various arrangements or dispositions of parts may be adoptedfor the passage or circulation of the steam through the radiator.

I claim The combination of the lower return-elbows D, havingdrip-openings b, with the lower horizontal base or pipe E for the waterof condensation, the vertical pipes A, and the upper elbows C,substantially as specified.
